Homebrew Core

Core formulae for the Homebrew package manager.

Update Bug

If Homebrew was updated on Aug 10-11th 2016 and brew update always says Already up-to-date. you need to run:

cd "$(brew --repo)" && git fetch && git reset --hard origin/master && brew update

How do I install these formulae?

Just brew install <formula>. This is the default tap for Homebrew and is installed by default.


First, please run brew update (twice) and brew doctor.

Second, read the Troubleshooting Checklist.

If you don’t read these it will take us far longer to help you with your problem.



Creating new formulae, updating existing ones, and fixing build issues is easier than you think!

Try brew edit $FORMULA and see how you fare.


brew help, man brew, Homebrew/brew’s README or check Homebrew’s documentation.
